LANDLORDS who allow their properties to be used for unauthorized group rentals, and those who illegally modify buildings for such purposes will from next month have the offense noted in their personal credit records, the Shanghai Housing Management Bureau said yesterday.

Such a black mark could limit a person’s access to government services like low-cost housing, Xin Yiming, director of the bureau’s management department, told a press conference.

It could also hamper their chances of getting a bank loan or a job in the public sector, he said.
